How to Reset Your AC Unit

Guide to Reset An Air Conditioning Unit

If you've been without power for an extended period of time, there's a good chance your AC unit has gone out. If this is the case, it's important to know how to reset your AC unit safely and effectively.

In this blog post, we will walk you through the steps to reset your AC unit. We'll also explain when it's necessary to reset your AC, and what to do if it doesn't seem to be working properly.

When Should I Reset My Air Conditioner?

There are a few different scenarios where you might need to reset your AC unit. If you've been without power for an extended period of time, if your AC unit has been turned off for an extended period of time, or if your AC unit isn't cooling properly, it's likely that you'll need to reset the unit.

Resetting the AC can help issues like a broken unit that only blows warm air and you need to correct the settings. Also, if you're experiencing problems with your thermostat, even when it's set to cool, resetting the air conditioning unit will help errors on the thermostat.

If you believe you may need an extra opinion about whether or not the issues with your air conditioner mean you need to reset it, you should contact a professional HVAC technician by requesting an appointment. A technician will consider the issues listed above, along with diagnosing the unit for additional reasons as to why your unit may need a reset.

Keep reading for steps on how to properly reset your AC unit.

Step One - Power Off the Unit

The first step is to power off the unit. You can do this by finding the reset button, holding it down, and powering it off. The button is usually a small, red button and can also be found using the owner's manual if you have it. Once the unit is off, you'll need to wait a few minutes before proceeding to the next step.

Step Two - Go to the Circuit Breaker

Now that you've powered down the unit, you need to find the circuit breaker box. It's usually somewhere easily assessable like the garage, basement, or laundry room. Once you've found it, locate the breaker that powers your AC unit and flip it to the off position.


Just like with step one, you'll need to wait a few minutes before proceeding to the next step.


Step Three - Wait a Few Minutes

For most circuit breakers, you only need to wait about 60 seconds before flipping the switch back on to turn on the power to the AC unit. If your breaker requires a few extra minutes, wait it out before turning the power back on.

Step Four - Turn On the Circuit Breaker

If you also turned off the power to the AC unit using the circuit breaker, you will need to flip the switch back to restore power to the unit. Then, you can go back to the unit and hold down the reset button to turn the unit on.

Step Four - Hold Down the Reset Button

Go back to your unit and hold down the reset button to turn the unit back on. Press down for three to five seconds and then release the button. Double-check that all buttons are switched to the "on" position, this includes the AC unit and the circuit breaker.

Step Five - Adjust the Thermostat

Once all power has been restored, it's time to adjust the thermostat. Adjusting the thermostat helps you know whether or not the unit has power.

Step Five - Confirm the AC Unit is Working

Finally, you can sit back, relax, and enjoy the cool air! If your AC unit has power and the thermostat is at the correct temperature with no errors, and you feel the cold air from the vents, your unit is now back up and running!
